Found a 1.8 16v at the JY today 375$
Heres what it needs from what i gathered for this to work:
Scirocco Exhaust Manifold and Downpipe
Internal Central Electric Wiring harness
16v Pressure plate + Clutch
Distributor
ECU
Now I have a few questions for those that have done this swap.
1. Can i use the CIS in the rabbit 8v right now for this? And if so can i just get the Scirocco intake manifold so it will remain on the right side or should i just go with what it has a get a CIS setup for the left side or how does that work??
2. Can I use my 8v Alternator to bolt up to the 1.8 16v?
3. Can I use my 8v Fuel Pump?
4. Do I HAVE to change axles since I'm using the existant GTI tranny but upgrading its internals?

I'm sure i left alot out, so if someone has this whole kit for sale lemme know im more than interested and would be happy if i didn't have to search all over gods green earth to find each part. I want this swap bad so if you can fill me in on anything i MUST have or i left out PLEASE tell me so i can make a checklist what to get if no one on here offers there swap for sale. If there is any websites with checklists let me know as well.
Please post guys i need ur help

Re: Checklist for Rabbit 16v Swap?? Anyone have a 16v Ready Swap for My Rabbit?? (BadasslilGTI)

What clutch you need depends on what tranny you have. 16V trannies have a larger input shaft.
1. You can use the CIS, but you need to be careful with your timing so's not to ping. You can use the manifold and airbox that goes to either side, but it gets harder with the A2 style, since the box is too big and there's more wiring to do that way.
2. Sure, but depending on what alternator/pulley you have now, there could be varying amounts of work involved. I actually had a rabbit alt. mounted on a 16V using part of a coil spring clamp kit. Eventually I went to a 16V alt. for the fit and the amps.
3. Sure. You might want to add the in-tank pump; it should just plug right in... I think.
4. Nope. But you might have to replace/rebuild them more often. The guy who now owns my 16V bunny had the left inner joint go KABLAMM! on him... while he was in the middle of getting all over the loud pedal.
You should consider finding the CIS-E system so you can safely advance your timing. If you do, the best way to go about it is to get the whole engine compartment harness out of a Scirocco- better to splice everything near the fuse box, than under the hood.
One little CIS-E gotcha that I ran into- The air flow plate potentiometer. On my wife's 16V 'rocco, it connects to it's wiring at a right angle to avoid getting squished by the battery, but for some reason on my rabbit it came straight out... half-broken, brittle wires make for an interesting intermittent hesitation problem.

Re: Checklist for Rabbit 16v Swap?? Anyone have a 16v Ready Swap for My Rabbit?? (simon_reinhardt)

I'll be doing this same swap soon(I hope), except that I have an entire 16v RoccoII to grab goodies out of.
I've heard from a couple people that if I want to use the CIS in the Rabbit, that i should use a Euro injection(lose the O2 sensor), and I could splice in just the knock sensor stuff, but i don't have to... And I don' know if I could splice in the whole harness
...Wiring makes my head ache...
Using the Euro injection, should I use the Rocco or RabbitGTI injectors? or do injectors come with the Euro unit, and should I use those?
Hey lilGTI, is your motor Rocco or GTI/Jetta? What do you think about what I stated above? Will it make life easier or more difficult?

This engine i found is out of a GTI...as far as what you said, i guess i might need to do some homework on all this

hehe Jay, I'm doing homework already and I plan to do a mk1 16V next winter
(Jetta Coupe!)
Good luck with it bro.

Sid- if you have the whole car available, why not grab the entire wiring harness? No splice problems that way. Also, take into account the "air shroud" issue with the injectors... the 16V head will expect them.

Don't get depressed. The airbox can be made to work, it's just a matter of some surgery to shorten it a bit. And re-routing fuel hoses somewhat. And I think there's just two harness plugs that go to the fuel meter, so it's not like you have to lengthen a million wires, just 5 I think.

I'm doing the swap with the euro injection. My thought is this: CIS Lamda and CIS E are for emissions, not for performance. All they ever do is take fuel away to make the mixture closer to stoich (maybe on the lean side, someone correct me if I'm wrong). This seems to lead to leaning problems on the high end. So, if you set your car up using the euro injection you will be stoich to rich without leaning out up top. I will however use the CIS E ingnition stuff. It advances timing until knock is sensed. This way you have optimal timing advance no matter what fuel you use. It will still be advantageous to use premium but not needed if you can't get it.

Well, part of my problem is, I'm going to have to do this semi-quickly. When my roommaye moves out, he's taking Lola. So we'll only have Ute and Brigitte. I would just drive Ute the way she is, but the tranny is screwed...No 1st & 2nd gear.
New Thought: Maybe I could just do a tranny swap(out of the Rocco), pick up the alternator I need and run Ute that way until I put together enough info/parts/bread to do the swap right... I don't wanna half-ass my way through this. Trouble is, I might HAVE to...
Now I'm thinking tranny swap for now... Hmmmmmm...Intriguing...
Thanks for the info everybody, keep it coming, I'm putting it all together in a file... http://****************.com/smile/emthup.gif http://****************.com/smile/emthup.gif http://****************.com/smile/emthup.gif http://****************.com/smile/emthup.gif http://****************.com/smile/emthup.gif

I 2nd that....this is a really strong thread with good points on swapping into Rabbits. Bring forth your best info and make this the thread to look for, for future swappers

Don't forget the exhaust system issue- a 16V will run nicely with the stock 2.25" stuff, which is substantially larger than a stock bunny. And a full-size 16V muffler won't fit in a Rabbit, so you either have to get a small high-flow model, or trim your spare tire well creatively.
Another nice touch is to get the charcoal canister and plumbing out of a 'rocco, since it hides more stuff (like the vacuum valve) under the fender. Or just look over the setup, and roll your own.
Unless you do a LOT of splicing, you're going to have all 3 computers wanting to be up in the cowl space. I'm not sure if the Scirocco's bracket will fit, but it's definitely worth finding out. Otherwise they'll just kinda flop around in there.
Jeez, this is turning into the how-to post from Hades, huh? http://****************.com/smile/emthup.gif

There are some links on my site that offer some testimonials on the A1-16V swap. For simplicity, I would go with the 16V Scirocco set up using the air box where it is. You can do the Scirocco 16V wiring in the engine bay (all you need is voltage) to get the computer and knock sensors going. You can use your existing 8V fuel pump.
Thanks,
Jim

I'm using a 9A engine in my Rabbit GTi .
The only thing you need to do is find a set of PL wiring loom and
ICU to solve your ignition problem together with the knock sensor.
Secondly the exhaut system.
Other than that no other issue.
